I am very soon going to be the lucky owner of the C-Six and need a recommendation on a zippered hard case to tote them around in as they will 100% be wearers for me. I like the hardcase that came with my X-Squared and I use the zippered Oakley vaults for my watch collection so something like that case would be great unless you have a better suggestion. I want something appropriate to protect a $1,500 dollar pair of sunglasses. Which size Oakley zippered hard case works best? Does the X-metal hard case work? Is there a nice case made by another manufacturer that will work better then something Oakley sells?
